Iphone: Alert View 2

Here we learn other things related to the UIAlertView Of iphone Application:

• Alter View with multiline Button:
• Alter View with Text field:

Alter View with multiline Button:

By default, if Alert has Three Button then its Come in Three line as

UIAlertView *alert = [[UIAlertView alloc] 

  initWithTitle:@"kamal " 

  message:@"Good Bye......." 

  delegate:self cancelButtonTitle:@"Cancel" 

  otherButtonTitles:@"hi", @"Hello ", nil]; 

    [alert show];

But If We Want to display Two Button with two different line then use below statement only before alert Show:

[alert setNumberOfRows:2];

Alter View with Text field:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Send Email" message:@"" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Send", nil];

CGRect frame = CGRectMake(14, 35, 255, 23);

UITextField *emailField = [[UITextField alloc] initWithFrame:frame];

emailField.borderStyle = UITextBorderStyleBezel;

emailField.textColor = [UIColor blackColor];

emailField.textAlignment = UITextAlignmentCenter;

emailField.font = [UIFont systemFontOfSize:14.0];

emailField.placeholder = @"";

emailField.backgroundColor = [UIColor whiteColor];

emailField.autocorrectionType = UITextAutocorrectionTypeYes; // no auto correction support

emailField.keyboardType = UIKeyboardTypeEmailAddress; // use the default type input method (entire keyboard)

emailField.returnKeyType = UIReturnKeyDone;

emailField.delegate = self;

emailField.clearButtonMode = UITextFieldViewModeWhileEditing; // has a clear 'x' button to the right

[alert addSubview:emailField];

[alert show];

[alert release];

Thanks

Iphone: Alert View

Here we learn about the UIAlertView Of iphone Application: just how to show the Alert Messages in Iphone Application.

Alter View:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"" message:@"MSG" delegate:nil/self cancelButtonTitle:@"OK" otherButtonTitles:@"cancel",nil]; 

alert.tag = 1;

[alert show];

[alert release];

- (void)alertView:(UIAlertView *)alert clickedButtonAtIndex:(NSInteger)buttonIndex

{

     if(alert.tag == 1)

     {

        if(buttonIndex == 0)

             // statements

else

  //statements

       

     }

}

Change UIAlertView Button Color:

Create the object of UIAlertView , the call automatically following method:

- (void)willPresentAlertView:(UIAlertView *)alertView 

{ 

[[[alertView subviews] objectAtIndex:1] setBackgroundColor:[UIColor redColor]];

    /*

      Here index 0 = Title , 1 = cancel Button , 2,3.... = otherButton

*/ 

} 

Alter View without Button:

UIAlertView *baseAlert = [[UIAlertView alloc] 

initWithTitle:@"" 

message:@"Message to user \n with asynchronous \ninformation" 

delegate:self cancelButtonTitle:nil 

otherButtonTitles: nil]; 

[NSTimer scheduledTimerWithTimeInterval:2.0f target:self selector: @selector(performDismiss:) userInfo:nil repeats:NO]; 

[baseAlert show]; 

baseAlert.frame = CGRectMake(0,190,320, 120);

- (void) performDismiss: (NSTimer *)timer 

{ 

[baseAlert dismissWithClickedButtonIndex:0 animated:NO]; 

} 

Thanks
